refactor: enhance authentication and access control in ProtectedRoute component

- Updated the ProtectedRoute component to improve access control logic, including a timeout mechanism for handling authentication checks.
- Refactored the checkAccess function to streamline user access verification based on roles and authentication status.
- Added comments for clarity on the authentication flow and the use of the convexClient plugin in the auth.ts file.
- Improved the overall structure and readability of the code in auth.ts and ProtectedRoute.svelte.
